How official OEM data and standardized State of Health (SoH) metrics are shaping the future of the global used EV market. As the secondary electric vehicle (EV) market rapidly expands worldwide, one question continues to dominate transactions: What is the true state of the battery?
Uncertainty around battery degradation remains one of the largest friction points for dealerships, fleet managers, and retail buyers. Today, France is taking a decisive step toward eliminating that uncertainty, and setting a precedent.
France’s Ministry of Economy recently introduced a standardized framework (Fiche TRA-EQ-133) for used EV purchase and lease subsidies (CEE grants). The policy establishes a clear rule: to qualify for government incentives, a used EV must prove a State of Health (SoH) of 80% or higher.
The text indicates that the French government recognizes direct extraction from the manufacturer’s BMS data as the standard method for determining the SoH. Other methods of SoH calculation are permitted, on the condition that the calculation process is explicitly detailed in the certificate. This decision officially cements manufacturer-based SOH as the commercial gold standard for used EV transactions—validating the core philosophy behind Moba’s solutions.
Moving beyond estimates: Why official BMS data matters
By mandating SoH OEM (the manufacturer’s official calculation directly from the BMS), regulators and industry leaders are choosing verifiable data over statistical guesswork. Official guarantees and government incentives require absolute accuracy and traceability.

“The adoption of the manufacturer’s SoH method by the government and major automotive players validates our conviction: transparency isn’t built on theoretical or statistical estimates, but on real data communicated by each individual vehicle. Professional partners now have a fully compliant tool to trigger government subsidies and reassure buyers.” — Guillaume Hébert, Co-Founder & CEO of Moba.
Setting the global benchmark: Battery health to full-vehicle insights
Moba Certify Pro was designed specifically around this standard. By transmitting official BMS State of Health without arbitrary recalculation, Moba delivers the integrity, speed, and transparency required by professional automotive players worldwide.
Moba goes beyond simple surface-level data to provide deeper technical value:
- Cell-level deep diagnostics: Evaluates the state of individual cells within the pack to uncover hidden imbalances.
- OEM warranty alignment: Returns the official OEM SoH metric—the exact value needed to activate or uphold manufacturer battery warranties.
- Advanced features: Includes comparative scoring, range estimation grid calculation, pack balancing issue detection, battery replacement identification, and more.
Industry leaders rally around standardized transparency
The move toward standardized battery certification is already gaining strong support across the automotive remarketing ecosystem. Key French players see this standard method for battery health as essential to accelerating used EV adoption.
“Transparency regarding battery condition is one of the key levers to overcome purchasing barriers for used electric vehicles. By relying on trusted partners like Moba, we provide our customers with certified battery health information and the transparency necessary to buy their next vehicle with confidence.”— Fabrice Farcot, Sustainability Director at Aramis Group
What this means for international markets

While this specific grant applies to France, the implications are global. As countries establish incentive programs and EV passports, standardizing around the State of Health will become key, while protecting residual values for leasing companies, fleet managers, and auction platforms, ultimately building clear consumer trust across international markets.
Today, Moba powers battery diagnostics for over 1,500 partners across 40 countries. As regulatory frameworks evolve, having a fast, compliant, and scalable diagnostic tool ensures automotive businesses stay ahead of compliance needs while building trust with every transaction.
